    SC-645 entry
    Finding type
    vessel_history
    Finding
    Archived NHHC DANFS entry identifies SC-645 as built by Peterson Boat Works at Sturgeon Bay, Wisconsin; laid down 1 February 1942; launched 26 July 1942; commissioned 12 September 1942; and transferred to the Maritime Commission 5 March 1948.

    Limitations
    The live NHHC URL returned HTTP 404 on 2026-10-03, so this is explicitly an archived NHHC capture. It documents identity and milestones, not vessel materials, asbestos content, exposure, causation, or later disposition after the Maritime Commission transfer.

    Finding
    NARA’s Special List No. 44 indexes deck-log holdings for SC-645 for 11 September 1942-30 April 1943 and 1 July 1943-30 June 1945.

    This is a holdings index, not the deck logs themselves. It establishes surviving date ranges for potential hull-specific research; it does not establish activity, materials, asbestos content, exposure, or the precise commissioning date.

    NHHC SC-645 entry; NARA PDF p. 106, SC-645 entries
    Finding type
    vessel_history
    Finding
    The authoritative hull-specific records reviewed identify the vessel as SC-645. This record therefore corrects and excludes the unsupported PC-645 vessel identity; PC-645 is not used as an alias or as a vessel-history finding.

    Study period

    Limitations
    The cited records positively identify SC-645; they do not themselves supply a complete numbering-history analysis for every PC-class hull. This correction prevents an unsupported PC-645 attribution and makes no materials or asbestos finding.

  5. [5]U.S. GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (1979) [gao]

    Highlights; full-report search result identifies shipboard insulation, gaskets, and pipe-hanger liners
    Finding type
    asbestos_application
    Finding
    GAO documented Navy-wide use and removal policy for asbestos in Navy ships in 1975-79, including shipboard insulation and applications such as gaskets and pipe-hanger liners. This is Navy-program context only; it does not identify SC-645 or establish that any such material was aboard her.

    Population
    Navy shipyard workers at Long Beach and Norfolk Naval Shipyards; not SC-645-specific
    Limitations
    The GAO product page was live but its PDF returned HTTP 403 to direct retrieval on 2026-10-03. The report concerns 1975-79 Navy policy, decades after SC-645’s documented wartime log period; it is contextual evidence only and cannot support an inference that asbestos was installed aboard this hull.

  6. [6]CourtListener authenticated-search helper, required base query ‘USS SC-645,’ opinion search; pacing allocator response [court_record]

    Helper output, 2026-10-03: ‘COURTLISTENER PACING: the fleet-wide request budget is momentarily spent’
    Finding type
    litigation_documented
    Finding
    No CourtListener result is recorded because the required authenticated CourtListener sweep could not begin: the fleet-wide pacing helper twice reported that its shared request budget was momentarily spent before an API request was issued. Litigation status remains unsearched, not negative.

    Limitations
    This records a search-access gap, not a no-result finding. The remaining three mandatory base queries and this query’s actual API search were not run after the helper’s throttling instruction; no asbestos variant was run.

    No ship-specific asbestos survey, abatement record, material specification, or qualifying litigation record was located in the official sources reviewed for SC-645.

    Limitations
    A limited public-source search cannot establish that no such record exists. Deck logs are an archival lead and CourtListener was blocked by fleet pacing, so this is not a litigation negative and does not establish absence of asbestos aboard the hull.
